Posture control device for marine vessels

摘要

A number of embodiments of watercraft propulsion unit controls for optimizing watercraft performance and maintaining stability. Performance is optimized in the illustrated embodiments by adjusting the trim angle of the propulsion device and stability is maintained by changing either the trim condition or the speed of the propulsion unit. The desired posture may either be preset in response to an earlier stable condition or may be set upon reaching of optimum performance.
